i ordered the n516 7800gt from newegg, it turned out to be the n517. has the copper heatsink as was stock at 470/1100

when i try to update the bios with a n516 bios, it says that there is an id mismatch, that i have a n517. ive used an older n517 bios but can anyone give me the latest one from evga? i cant get it b/c you need to have the card resisterd but mine is begistered as n516
